## BEH-SOMA: Container
**Simplified behaviors**:
— ms:
- Resting at -70 mV: Leak channels + pumps (keep at resting)
-- ?
- VDB Depolarization : ~1-2 ms: Na⁺ enters (some VGSCs open)
- Opened VGSC remain closed for a refractory period
Spike if depolarized above threshold: to -50 mV
-- Here the threshold is based only on the integration of Na+
-- The threshold is tuned during the spiketrain. Low threshold at rest, to increase sensitivity, threshold increase during spike to increase discrimination
-- increase SpikeTrainTraces (fast at spike)
-- increase Ca2+ traces
- Repolarization to -70 mV: ~1-2 ms: K⁺ exits (VG K⁺ channels open) ← NOT pumps!
-- fast pump which decreases Na+, we do not model K+
- After-hyperpolarization: ~5-20 ms: K⁺ channels still open
-- must figure out how to deal with deoplarization
-- decrease SpikeTraintraces slow, only if away from spiketrain this is empty
— seconds:
- Return to exact -70 mV: ~100-1000 ms: Na⁺/K⁺ pumps restore gradients
-- slow pump
- Ca2+ accumulation: SpikeTrainTraces
-- ?
— mins:
- VGSC modulation

**Tubs:**
- **VDB**: dendrites deliver current
- **Na**: are a proxy for the Coulombs of charge building up on the somatic membrane. They are used to check threshold, but also to mimic Na+ and K+ pumping
- **AP**:
- **bAP**:
- **Ca2+**: Medium term traces to guide tuning and Night development
- **SpikeTrainTraces**: sono le tracce che consentono al neurone di far partire il Tuning neuronale, quando e' lontano da uno spike-train, ovvero e' in riposo.

### ms: behaviors SOMA
#### CheckVDB: Context
As dendrites deliver current (VDB), the soma acts like a capacitor. It "stores" this charge in the form of membrane potential. VSOMA is proxy for the Coulombs of charge building up on the somatic membrane.
